3801 Init TD Sensor
Do this SP after replacing the developer in one or more of the PCUs when servicing
the machine. This SP:
• Checks for the presence of developer in the development unit. (This ensures that
the film seal has been removed from the developer pack.)
• Initializes TD sensor. (Calibrates Vtcnt).
• Calibrates development gamma and calibrates toner density. Also does the
MUSIC check and correction.
Note: Do SP3811 after drum and cleaning blade replacement. SP3811 should
always be done at the following times:
1) During the machine installation procedure after the developer and toner have
been installed, and
2) During machine maintenance after a drum and cleaning blade have been
replaced.
In both cases, SP3811 prevents the blade from scouring a dry drum.

3802 TD Sn Init OK?
This SP displays the results of the TD sensor initialization with SP3801 001~006.
The machine returns the status of the previous initialization with numbers, 1 digit for
each PCU. The numbers are read in order as "K, M, C, Y".
Four numbers are used to indicate the status of the execution.
1: OK (success)
2: Cancelled (door opened, etc.)
4: Not executed (not selected for execution; this is not an error)
9: Vtcnt abnormal. Vtcnt (TD sensor control voltage) could not be adjusted to within
2.5±0.2V. The machine issued a TD sensor error for the PCU where there is a
problem (SC372~SC375).

These SPs should be executed after replacement of the drum cleaning roller or
cleaning blade.
